SBQuantum closes an oversubscribed $4M seed round, names Eric Giroux CEO, and launches a US defense-market sister entity (Zero Drift Technologies)
SBQuantum, the Canadian diamond-NV-center quantum-magnetometer company that two weeks earlier was selected for NOAA's MagQuest space mission, closed an oversubscribed $4M USD seed round co-led by Quantonation and Quantacet with participation from Investissement Québec. The company named Eric Giroux (previously CEO of RaySecur, security/defense background) as CEO; founder David Roy-Guay moved to Chief Technical Officer. SBQuantum also launched Zero Drift Technologies, a US sister corporation headquartered in Cambridge, Massachusetts, dedicated to serving American government customers and defense primes.
Second material SBQuantum event in the window — funding round plus CEO succession plus US-market-entity creation, all tied to the prior MagQuest selection. Meaningful for the quantum-sensing sub-domain (score 6) as a coordinated funding + go-to-market package; below score 7 because round size is small and the US entity is newly-formed.
Positions SBQuantum as the leading NV-center magnetometer player for US defense navigation and threat-detection applications, with a structural US/Canada separation that matches how Canadian defense-tech firms typically approach US procurement.
